Meteorite on Mars
The Opportunity rover is still chugging along after more than five years on Mars. Look what it recently discovered on its way to Endeavor crater.
Yes, that’s a meteorite. It’s about 2 feet across and composed of iron-nickel.
You can read more about it here. There’s a lot of interesting science behind this because the present atmosphere of Mars is too thin to slow down a meteorite this large enough to allow it to survive impact. In addition, it’s not sitting in any sort of crater. That means that it has moved since it landed. What caused it to move?
